Apple is now taking that extreme drive to makes its device thinner to the iMac. The new iMac is just 5mm thin, roughly 80 percent thinner than the previous generation model.

It includes an 80211n Wi-Fi, up to 3TB HDD, NVIDIA Kepler graphics, four USB 3.0 ports, GbE, Thunderbolt, and your choice of Core i5 or Core i7 processors. The new iMac also comes with 128GB of flash storage standard, which is then combined with 1TB to 3TB HDD.

Using what Apple calls "Fusion", the OS and all of your core applications are stored on the flash drive, while your user files and applications you don't use often are stored on the slower HDD. If you use applications that are stored on the HDD more often, they'll automatically be migrated over to the flash drive for faster access.
